Subject: [PATCH v3 06/13] drm: Allow driver-managed destruction of colorop objects
Date: Tue, 13 Jan 2026 15:52:56 +0530 [thread overview]
Message-ID: <20260113102303.724205-7-chaitanya.kumar.borah@intel.com> (raw)
In-Reply-To: <20260113102303.724205-1-chaitanya.kumar.borah@intel.com>
Some drivers might want to embed struct drm_colorop inside
driver-specific objects, similar to planes or CRTCs. In such
cases, freeing only the drm_colorop is incorrect.
Add a drm_colorop_funcs callback to allow drivers to provide a destroy
hook that cleans up the full enclosing object. Make changes in helper
functions to accept helper functions as argument. Pass NULL for now
to retain current behavior.
